HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 824, 653, 210, 788 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 824, 653, 210, 788 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 824, 653, 210, 788 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 824, 653, 210, 788 is 1.
HCF(824, 653, 210, 788) = 1
HCF of 824, 653, 210, 788 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 824, 653, 210, 788 is 1.
Highest Common Factor of 824,653,210,788 is 1
Step 1: Since 824 > 653, we apply the division lemma to 824 and 653, to get
824 = 653 x 1 + 171
Step 2: Since the reminder 653 ≠ 0, we apply division lemma to 171 and 653, to get
653 = 171 x 3 + 140
Step 3: We consider the new divisor 171 and the new remainder 140, and apply the division lemma to get
171 = 140 x 1 + 31
We consider the new divisor 140 and the new remainder 31,and apply the division lemma to get
140 = 31 x 4 + 16
We consider the new divisor 31 and the new remainder 16,and apply the division lemma to get
31 = 16 x 1 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 824 and 653 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(140,31) = HCF(171,140) = HCF(653,171) = HCF(824,653) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 210 > 1, we apply the division lemma to 210 and 1, to get
210 = 1 x 210 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 210 is 1
Notice that 1 = HCF(210,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 788 > 1, we apply the division lemma to 788 and 1, to get
788 = 1 x 788 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 788 is 1
Notice that 1 = HCF(788,1) .
